What is RAID? If you’re not an IT person, you probably don’t know a lot about it. However, one thing is for sure. You’ve probably heard about it. If you’re working in an office where massive data are stored in servers, you’ve probably come across the RAID acronym.
Companies rely a lot on RAID systems. For starters, they're very cost effective. Secondly, they can help lessen the impact of a data loss.
So, what does the acronym, RAID, stand for. Well, it stands for Redundant Array of Inexpensive Disks. Originally, it stood for Redundant Array of Inexpensive Disks.
This particular data storage technology basically uses multiple disks or drives to achieve better reliability and performance.
There are various RAID levels. Each RAID level is defined by the way the disks are joined.
Here are two examples of RAID levels. RAID 0 consists of two drives or more. What this level does is that it strips data across all of the drives. By doing that, you are able to maintain your capacity and at the same time, double the read and write performance. Unfortunately, you will lose some data in case one of the drives fail. RAID 0 is ideal if you back up your data regularly. RAID1 is more reliable since it can retain data in case one of the two drives fail. As you can see, the various RAID levels provide some kind of safety net in case of hardware failure.
So how reliable are RAID-enabled systems? According to https://www.harddriverecovery.org/raidcenter/raid-drive-failure.html, they are very reliable. As a matter of fact, they can operate smoothly for years.
However. RAID-enabled systems are not perfect. You would also have to consider the mechanical nature of their main components. They can also be prone to failure in the future. Another thing to consider is the impact of Undetected Disk Errors (UDEs) in RAID-enabled systems.
Considering the possible failures of RAID systems, you would have to rely on experienced RAID data recovery engineers. To find them, you can check out https://www.harddriverecovery.org/raid-data-recovery.html.
